Running shoes: your mileage may vary

Adrenaline and Kinvara are best in the long run

Today's run (treadmill): 25 minutes

I like running shoes for the same reason I like sports cars. They are the only layer between you and the road and they're engineered to enable performance. If you use your imagination, sports cars and running shoes even look similar, sharing the same aerodynamic profile. The biggest difference between the two is that while anyone can go fast in a Porsche, the best thing a running shoe can do is optimize a runner's potential.

In the 4+ years that I've been running, I've acquired a number of shoes. Some of them were great and some are best forgotten. I started logging my workouts on Daily Mile in April of 2010 and that service provides me with a tool to track the mileage of my running shoes. With the exception of the first few pairs I bought back in 2008, I have a complete history of my time spent with every shoe that I've owned since late 2009.

Saucony Kinvara (original)

Brooks GTS 10

I recently exported my shoe mileage data and graphed it to visualize the range (above). When people tell me that they notice their running shoes breaking down after five months, I'm usually skeptical because my Brooks Adrenaline GTS 9's held up for more than 700 miles. My all-time favorite running shoe, the original Saucony Kinvara, performed well for almost 500 miles before giving out. I ran a little too long in those and suffered a bad knee problem due to it. Despite that, I still can't bring myself to throw them out.

My current shoes of choice are the Kinvara 3's for the road and, for the treadmill, the Pure Drift prototypes that I tested for Brooks. Had I requested size 11's instead of 10.5's for the Pure Drifts, I'd probably be wearing them more often. The fit in the toe box is just a little too narrow for my foot, so I don't use them for long runs on pavement.

The good thing about running shoes (vs. sports cars) is that you buy new ones often without breaking the bank. I suspect, based on history, that the Kinvara 3's will need replacement in the next few months. I'm tempted to replace them with the production version of the Pure Drift, but there are a couple of New Balance models that interest me. Plus, a whole new crop of 2013 models will soon arrive from the other brands.

While I'm thinking about it, it might be time to add a new trail shoe to my collection. Why not? It would certainly be cheaper than getting a Land Rover.

The shoe debate has ended

Yesterday afternoon I stopped by the Super Runner's Shop in midtown which is located a block from my office. I mentioned that I bought the Brooks Adrenaline 9's the previous day and was unhappy to later discover that they were a stability model. The man at SRS asked to look at my foot, said I had a low arch and told me that I needed a shoe that managed pronation like the GTS-9 or the Asics 2140. All the same he said he'd be happy to take back the Brooks if I was unhappy with them. I discussed all this later with AG and she said I shouldn't get hung up on whether a shoe is neutral or made for stability. The important thing was fit. I decided that I'd go back today and try on more shoes.

A funny thing happened when I got home and started packing up the Brooks for return. I'd thought about what the salesperson said about pronation and I looked at my Nikes to see if I could find evidence of that. I was very surprised to see that the outside edges of both soles (at the back) were worn quite a bit. I compared the back view of the Nikes with the back of the Brooks and saw how the Brooks were built to counteract that wear. Instead of boxing up the Brooks I tried them on again and then tried the Nikes. The fit of the Brooks was actually much better and my only issue was the tightness at the tongue. AG had told me that sometimes changing the lacing helps the fit of a shoe and I noticed that, unlike the Brooks, the Nikes did not have laces in the top holes. I took the laces out of the top holes of the Brooks, re-tied them and decided that they felt good enough for me to give them another chance.

This morning I gave the Brooks a true test on the treadmill. I changed the battery on the Garmin foot pod last night and was happy to see the 50 was once again recording distance so that wasn't going to distract me like it did on Sunday. I started at a comfortable pace and increased speed as I went. The Brooks felt very good, no complaints. I ended up running a couple of miles at an 8:39 pace. I didn't really push my speed during the run, if I had I'm sure I could have taken down the pace by ten seconds/mile.

So after all that I've decided to keep the Brooks. I told my wife this morning and she smiled and shook her head but supported me completely. I think I drove her a little crazy over the last couple of days obsessing about this purchase. I want to take the GTS 9's on a long run outdoors to really understand how they fully perform. Right now my feet and my leg feel pretty good. Brooks Adrenaline GTS 9's, I'm sorry what I said about you before. You're more than okay.
